What is the CoC Comet Sorceress Build?

The CoC Comet Sorceress build revolves around using the Cast on Critical Strike (CoC) support gem in combination with the Comet skill. The CoC mechanic allows your character to automatically trigger skills on critical strikes, which works perfectly with Comet, a high-damage cold spell that deals significant AoE damage around its impact zone.

What makes this build so powerful is the synergy between CoC, Comet, and critical strike chance. As you increase your chance to critically strike, your Comet spells will trigger rapidly, clearing packs of enemies with explosive effects and making your character a fast-paced, highly mobile sorceress.

Key Mechanics of the Build

Before diving into the specifics of the CoC Comet Sorceress, it's important to understand the core mechanics that make this build work:

Cast on Critical Strike (CoC):

CoC is a support gem that allows you to automatically cast a linked skill whenever you score a critical strike. This means that every time you critically strike an enemy, it triggers a spell for free. For this build, we link Comet to CoC, causing Comet to trigger on every critical strike.

Comet Skill:

Comet is a cold-based AoE spell that creates a projectile, dealing cold damage on impact. It has the added benefit of creating frost effects, which slow and freeze enemies, adding an extra layer of utility to the build. The Comet explosion scales with critical strikes and spell damage.

Critical Strike Chance:

The key to success in a CoC build is maximizing critical strike chance. The more often you crit, the more Comet spells get triggered, leading to massive AoE damage. You'll want to stack critical strike chance, spell damage, and cooldown recovery speed to make this build work smoothly.

Mana Management:

Since CoC and Comet are reliant on a lot of casting, mana management becomes a crucial part of the build. You'll need to balance mana regeneration, mana cost reduction, and efficient use of resources so that you can keep casting Comet without running out of mana.
